WASHING-MACHINE.

specification of Letters Patent.

Original application filed January 26, 1909, Serial N 0. 474,270. Divided and this application filed February To all whom it may concern:

Be it known that I, ORLAFH. WATKINS,

, a citizen of the United States, and a resiinexpensive and efficient power momentum device, and also equipped with novel means for transmitting energy to said momentum device, and for applying the stored energy to the reversely reciprocating rubber of the machine.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a vertical sectional view of a washer constructed in ac cordance with this invention.

Fig. 2 is a horizontal sectional view taken substantially on theline 22 of Fig. 1.

Fig. 3 is a detail plan view illustrating the arrangement of the gearing for reversely rotating the upper shaft.

Fig. 4 is a vertical sectional-view illustrating a modification of the invention.

Fig. 5 is a horizontal sectional view on the line 55 of Fig. 4.

Fig. 6 is a detail elevation illustrating the construction of the operating lever and the upright links of the washing machine.

Fig. 7 is a detail sectional view illustrating the construction of the slide.

Like numerals of reference designate corresponding parts in all figures of the draw- IHOS.

The power momentum device, illustrated in Figs. 1 to 3 inclusive of the drawings,

comprises in its construction a rotary frame Serial No. 10,021.

embodiment of the invention shown in Fig.

1, consisting of a continuous vertical shaft 5, having its upper end 6 journaled in a suitable bearing, of a horizontal bar or brace 7 and stepped at its lower end 8 in a suitable bearing 9, supported by cross bars 10, but the intermediate portion of the vertical shaft mav obviously be omitted without affecting its operation, the upper and lower journals only being essential. The horizontal top connectin bar is centrally secured to the upper end 0 the shaft 5, and its terminal portions 11 are bent downward and outward, being arranged at an inclination and pierced by the upper ends of the guide rods 3. The lower ends of the guide rods are suitably secured to the lower portion of the shaft The weights 2 are preferably in the form of balls, and their inward and outward movements are cushioned by inner and outer cushioning devices, consisting of coiled springs 12 and 13, disposed on guide rods at the inner and outer ends or portions of the slidable weights 2, which are provided with Patented Oct. 15, 1918.

openings 14: through which the guide rods pass. The terminal portionsll of the top connecting bar 4 are substantially perpendicular to the guides and are arranged to form abutments for the upper cushioning springs 13. The rotary momentum device is not of suflicient weight to appreciably affect the starting of the machine, but as the speed of the machine increases the weights are thrown outward and form an etlicient momentum device, rendering the operation of the mca-hine steady and uniform.

The momentum device will be found advantageous in manually operated machines,

and especially in those equipped with upwith a gear 22 of an upper or agitator shaft 23.

Figs. 4: to 6 illustrate a modification. The weights 24, which are in the form of balls, are carried by the lower end-s of thearm's or levers 25, located at opposite sides of a lowerrotary shaft 26, and connected at their upper ends with the same by a slide 27, and also connected at intermediate points with the said shaftby links 28. The shaft 26 is preferably square in cross section, and the slide 27 is in the form of spaced plates, lo cated at opposite sides of the shaft and pivoted at their ends to the upper terminals of the weighted arms or levers $25. The links 28 diverge upwardly and are connected at their lower ends to'the shaft bya suitable pivot 29. The upper ends ofthe links are connected with the arms or levers 25' by pivots30 and 'form-fulcrums for the weight carrying arms or levers. When the shaft 26 is rotated, the weights 24 move inward and outward as the speed of the shaft increases and diminishes. The weights are thrown upward and outward by centrifugal force and are moved downward and inward by gravity.

in suitable bearings, carries a pinion 31, meshing with a relatively large gear 32, which isconnected by a rod33 with an operating lever 34. A spring 35 is connected with the rod 33 to prevent a dead center.

The lever isconnected at the upper por-' tion by inner and outer links 36 and 37 with a rack bar 38, which .reversely rotates an agitator shaft 39 through a pinion similar tothat heretofore described. The upright links 40 and 41 are employed for maintaining the inner and outer links 36 and 37in operative position.

. What I claim is:

v 1. In apparatus of the class described, a balance governorcomprising a vertical shaft mounted for rotation, arms fixed to and extending horizontally in opposite directionsfrom said shaft and having their outer ends turned downwardly, rods mounted in in clined positions beneath said arms, said rods fixed at one end each to sald shaft, said rods extending outwardly from said shaft and fixed at their outer ends to the down-turned The verticalshaft 26, which is journaled ends of said arms, and weights slidingly mounted on the inclined rods.

2. In apparatus of the class described, having a vertical shaft, an automatic balance governor, comprising arms radiating from said shaft and having their outer ends turned downwardly, inclined rods fixed to the shaft below the arms and fixed to the down-turned ends of said arms, cushions on the outer ends of said rods, and weights slidingly-mounted on said rods.

In apparatus ,of the class described, a

naled within said support, a pair of diametsupport, a vertically extending shaft jourrically extending arms carried by the upper end of said shaft and extending equi-distant on. each side thereof, angular extensions formed at the extremities of said arms, sup-- porting rods connecting said iangular' extensions with the said shaft, weights slidably mounted upon said rods and arranged to be shifted outwardly :by centrifugal force due to the rotation of said shaft and cushioning members carried by each end of said weights to limit the movements thereof for the purpose specified. i

4. In apparatus of the class described, a power momentum device comprising a rotary shaft, outwardly extending rods secured to said shaft to rotate therewith, weights slidable alongsaid rods, means to normally cause said balls to move toward said shaft when at rest, means to rotate said shaft where by said balls will move outwardly from said shaft in proportionto the speed of rotation, and means for rigidly bracing the outer end of each of said rods against lateral movement.

- 5. In apparatus of. the class described, a power momentum device comprising a rotary frame journaled at the top and bottom and including upwardly diverging inclined guides, and a top connecting bar secured at its terminals to the upper ends'of the guides, and weights slidable along the guides.

6. Inapparatus of the class described, a power momentum device comprising a 1'0- taryframe including upwardly diverging inclined guides, upper and lower journals arranged at the top and bottom of the frame, and a top bar connecting the guides and having inclined terminal portions,

weights, slidable along the guides, and cush- 'iomng means supported by the guides and locatedabove and below the weights.

In witness whereof, I hereunto subscribe my name this 2nd day of January, A. D. 1915. v
